What happened
On August 16, 2017, police officers conducting an anti-drug operation in Caloocan City detained 17-year-old Kian delos Santos. Witness accounts, forensic findings and later court rulings established that officers took him to a secluded area where he was killed. The officers maintained that the shooting occurred during a lawful operation, a version later rejected by the courts.
Investigation and prosecution
Arnel Oares, Jeremias Pereda and Jerwin Cruz were prosecuted for murder. The case became a prominent test of criminal accountability for police conduct during the Philippines' anti-drug campaign. Prosecutors relied on eyewitness testimony and forensic evidence, while the defense challenged witness credibility and argued that the officers had been performing official duties.
Convictions and appeal
The Regional Trial Court convicted all three officers of murder, and the Court of Appeals upheld those convictions. The case then reached the Supreme Court, which reviewed whether the evidence proved the elements of murder and whether the officers could rely on the performance of official duties as a defense.
Supreme Court ruling
In a decision dated August 11, 2025, publicly summarized by the Supreme Court on December 22, 2025, the Court affirmed the murder convictions of Oares, Pereda and Cruz. It found that treachery was established and that the killing was neither necessary nor justified by police duties. The Court imposed reclusion perpetua and ordered damages, while modifying language concerning parole eligibility.
Why the case matters
The ruling is significant because the country's highest court expressly rejected the argument that unlawful killing could be treated as part of ordinary police performance. It also shows how witness testimony, forensic evidence and appellate review can converge in a prosecution involving state agents.
